Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has made an assessment of the potential merits of the use of air curtains in indoor settings to help prevent the airborne transmission of covid-19.

DfT is considering a range of potential engineering mitigations for Covid-19 on the transport network. We are following advice from SAGE which has considered the potential benefits of improved ventilation flows, however to date no assessment on the use of air curtains directly has been made.

We are aware that experts are producing guidance such as the CIBSE Covid-19 Ventilation Guidance and the REHVA Covid-19 Guidance.
